VC与linux通过socket通讯

参考：http://www.cnblogs.com/skynet/archive/2010/12/12/1903949.html

socket编程大家都很熟悉，我在这里就不再罗嗦了。直接切入正题。

该程序分两部分，server端和client端（谁都知道）。其中server端采用windows平台，那linux平台当然是client端了。

这里是server端程序：

/**********************************/

/* it worked as server under windows platform */

/* written by mlsx 1998-2-7                     */

/************************************/
include <windows.h>

#include <stdio.h>

#pragma comment (lib,"WS2_32.lib")

#define USERPORT 10001

#define HOST_IP_ADDR "127.0.0.1"

main(int argc,char *argv[])

{

 char buf[128];

 SOCKET s,ns;

 struct sockaddr_in client;

 struct sockaddr_in server;

 int namelen,pklen;

 int status;

 WSADATA wsd;

 if((status=WSAStartup(MAKEWORD(2,2),&wsd))!=0)

 {

  perror("wsastartup() failed:");

   exit(1);

 }

 if((s=socket(AF_INET,SOCK_STREAM,0))< 0)

 {

  perror("socket failed :");

  exit(1);

 }

 ZeroMemory(&server,sizeof(server));

 server.sin_family=AF_INET;

 server.sin_port=htons(USERPORT);

 server.sin_addr.s_addr=htons(INADDR_ANY);

 if(bind(s,(struct sockaddr *)&server,sizeof(server))<0)

 {

  perror("bind() failed:");

  exit(2);

 }

 if(listen(s,4)!=0)

 {

  perror("listen()failed :");

  exit(3);

 }

 while(1)

 {

 namelen=sizeof(client);

 if((ns=accept(s,(struct sockaddr*)&client,&namelen))==-1)

 {

  perror("accept()failed:");

  exit(4);

 }

 printf("accept successful");

 for(;;)

 {

  if((pklen=recv(ns,buf,128,0))<0)

  {

   perror("recv() failed:");

   exit(5);

  }

  else

   if(pklen==0)

   {

    printf("recv():return FAILED,connected is shut down");

    break;

   }

   else

    printf("recv():return success,packet length=%d context is %s\n",pklen,buf);

  

  Sleep(1);

  //printf("the buf is %s\n",buf);

  if(send(ns,buf,128,0)<0)

  {

   perror("send() failed:");

   break;

  }

  else

   printf("send() return success packet length is %d\n",pklen);

 }

 }

 closesocket(ns);

 closesocket(s);

 printf("server ended successfully\n");

}

 

这里是client端程序：
